Design for Reliability of Phased Array Radars
2021 6th International Conference for Convergence in Technology (I2CT), 2021Reliability in Phased array technology has been evolving steadily since it was first conceived. Various approaches for establishing reliability are dealt in this paper towards building a reliable system. The methodology adopted was initially carrying out reliability analysis through parts stress method, RBD using functional flow diagram with study of ...

Electronics & Communication Engineering Journal, 1990
Array antennas were used in early radar systems. Today's microwave phased arrays with electronic beam-steering allow surveillance and tracking with variable data rates in a multifunction radar. The paper reviews system options and discusses the engineering of active arrays, using as an example the Siemens Plessey Radar/ARE MESAR, which is now ...

The Jicamarca phased-array radar
2013 IEEE International Symposium on Phased Array Systems and Technology, 2013Phased array and spaced antenna radar techniques developed and employed at the Jicamarca Radio Observatory for ionospheric research are reviewed. The ionospheric scatterers studied by Jicamarca are not spatially homogeneous and not beam filling in some cases, and distinguishing the bearing of the radar backscatter is essential for correctly ...

IEEE Spectrum, 1968
An array antenna can enlarge the capability of a radar system by contributing beam-pointing agility as well as providing a way of handling large power. The fundamental theory of such antennas was outlined in IEEE Spectrum exactly four years ago.1 Advances in the art have been so impressive that this month's Proceedings of the IEEE is a special issue on

Calibration of a Digital phased Array for polarimetric Radar
2010 IEEE MTT-S International Microwave Symposium, 2010When an active phased array is used for polarimetric radar applications, the system must be calibrated to reflect the fact that polarization of the transmitted and received fields is dependent on the scan angle. This paper discusses the challenges of polarimetric phased array calibration, and demonstrates these techniques using a linear array of eight ...

Solid state phased array radar
1974 Antennas and Propagation Society International Symposium, 1974The system advantages and limitations imposed by the solid state phased array radar are reviewed. The implications of these factors on the radar subsystems are discussed and the characteristics of the U.S. Army test bed solid state radar are presented.

Phased-Array and Radar Breakthroughs
2007 IEEE Radar Conference, 2006Many think that radar is a mature field, nothing new to happen, it having been around a long time. Nothing can be further from the truth. When I entered the field in the '50s I thought the same thing. The MIT Radiation Lab. Series 28 book volume set summarizing the highly classified World War II work on radar was just published and provided the ...

Abstract : Research effort was directed toward the investigation of components, techniques, and fundamental theoretical limitations of arrays for long-range radar applications. Research on components for arrays includes low-noise RF amplifiers, highpower modular transmitters, high-speed building blocks for data- processing systems, high-speed microwave

AIP Conference Proceedings, 1988
Large phased‐array radars can play a very important part in arms control. They can be used to determine the number of RVs being deployed, the type of targeting of the RVs (the same or different targets), the shape of the deployed objects, and possibly the weight and yields of the deployed RVs.
